DEVICE FOR EVALUATING CHARACTERISTICS OF ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a characteristic evaluation device for evaluating the temperature characteristics of a photoreceptor at low cost with high accuracy, while keeping versatility, concerning a photoreceptor characteristic evaluation device.

SOLUTION: In the photoreceptor characteristic evaluation device, a charging device, an exposure device, a surface potential detecting device and a destaticizer are arranged around the photoreceptor. The photoreceptor characteristic evaluation device includes a heating device heating the photoreceptor, a controller controlling the output of the heating device, and a temperature sensor measuring the surface temperature of the photoreceptor and is configured so that the heating device and the temperature sensor can be moved in the axial direction of the photoreceptor and the centers in the axial direction of the photoreceptor of the charging device, the exposure device, the surface potential detecting device and the destaticizer coincide with each other. An area occupied by each of the charging device, the exposure device, the surface potential detecting device and the destaticizer in the axial direction of the photoreceptor is within an area occupied by the heating device in the axial direction of the photoreceptor. The relation of the length L1 in the axial direction of the heating area of the heating device, the total length L of the photoreceptor, and the length L2 in the axial direction of the charging area of the charging device is L2≤L1COPYRIGHT: (C)2011,JPO&INPIT
